ABSTRACT We address the problem of robust video transmission over
unreliable networks. Our approach employs the principle of
multiple-descriptions, through pre- and post-processing of the video
data, without modification to the source or channel codecs. We employ
oversampling to add redundancy to the original video data followed by a
decomposition of the oversampled video frames into "equal" sub-images
which can be coded and transmitted over separate channels. Simulations
using two descriptions show that this approach maintains excellent
reconstructed video quality when only one description is received
